业务层调用FeignClient没加GlobalTransactional注解就报错

当前业务层服务通过feignclient调用其它服务，方法上或类上没有配置GlobalTransactional注解就报错，

Start from the reported stack trace in SeataHystrixConcurrencyStrategy$SeataContextCallable and RootContext.bind, then inspect how a Feign call without GlobalTransactional propagates context through Hystrix. Reproduce the failure in the relevant sample and verify that the call no longer raises the xid-must-be-not-blank error.
